This paper provides an overview of the heat losses through the thermal bridge in the junction between a wall and a slab on grade at the perimeter of the foundation. First, the paper discusses the heat losses through the thermal bridge. In particular, the additional heat loss through the thermal bridge due to floor heating. In addition, the paper provides a thorough description of the total heat loss through the thermal bridge in the junction slab on grade and the wall. The result may be used in order to calculate the heat loss through the building envelope of a building.
